I had a great time during my stay (4 nights) at Geof's place. The room is large, clean, well lit with a nice window opening to the courtyard, and the bed is very comfortable. The bathroom was also very clean. There is a short walk to a major train station taking you quickly to all the major spots in Berlin.
I went out a couple nights with Geof and some friends of his, and I had a great time with them. A funny, laid back, enjoyable crowd. And their neighborhood (Friedrichshain) is one of the coolest in the world. So many great bars, restaurants, cafes, parks, etc. You'll have a hard time finding a better deal in Berlin than Geof's listing.

OK Geoffrey: friendly man
OK House Position: near Warschauer Straße (S & U Bahn) and into a great entertainment district
OK Guest Room: large room and comfortable bed but NO wardrobe/locker inside and NO key to the door
NO Toilet: too small, NOT very clean and NO key to the door

We had a superb stay at his place. Neat room and a perfect location. What else does one need? As they say in real estate: Its all about location, location, location. But when you're host is also nice and helpful, this makes it even better. Thank you for having us!

Geofrey is warm and relax person, he told me about Berlin and where to go. The house is easy to find, 200 metres odd from the nearest metro station. Internet and central heating works properly. The room is spacious and has everything you need. A little small bathroom.

Geoffrey is really nice and relax. We had good time with him. The bathroom is really small and not as clean as I like but the room was nice and spacious. There is lot of clubs, restaurants and bars just near the apartment +1 ;)

The room is clean, the bed is comfy and as advertised, the location could not be better! Tons of interesting restaurants and bars within a stone's throw. Geoff is also a very friendly and accomodating host!

My friend and I had a lovely stay at Geof's place! It is in a perfect location - great if you're looking for an experience in Berlin from more of a local's perspective - close to transit links, cafes, bars... Geof was very friendly and gave us some great suggestions/tips about Berlin as well. I would definitely stay there again if I go back. Thanks Geof!
